Chemical Properties
Orange crystalline powder
Uses
5-Bromoisatin is used in the synthesis of N-derivatives of 5-bromoisatin, N-substituted pyrroles, linear polyaryleneoxindoles, 5-bromodioxindole, cinchoninic acid derivatives, 3-hydroxyoxindole, S-benzyldithiocarbazate Schiff Bases, 5-bromooxindole and Morita-Baylis-Hillman adducts of isatin derivatives. It is an indole derivative.
General Description
5-Bromoisatin is a 5-haloisatin. One of the methods reported for its synthesis is by reacting N-halosaccharins with isatin in the presence of SiO2. Its inotropic activity has been studied on rhythmically stimulated papillary muscles of guinea pigs. It is reported to exhibit analgesic and sedative properties at a dose of 0.2g/kg in mice.
Purification Methods
5-Bromoisatin forms red prisms or needles from EtOH. The N-acetate crystallises as yellow prisms from *C6H6, m 170-172o, and the N-methyl derivative forms orange-red needles from MeOH, m 172-173o.
